Satellite Polarization Offset

Float
-180 - 180 (deg)
The pol correction to be added to the calculated pol
position during the targeting sequence.
Use Secant Correction
4
Choice
“Yes”, “No”
Flag indicating whether to use a SECANT correction
on azimuth scans
Disable Scans
4
Choice
“Yes”, “No”
Flag indicating that a compass scan over the target
should not be run (yes = do not run scans)
Satellite Polarization Offset is used to include the published linear polarization offset, or skew, for
the Target Satellite in the POL pointing solution. For example, Eutelsat’s fleet of satellites employ a
3.5 degree skew in their linear polarization vector.
The use of Secant Correction is determined by the design of the antenna system. This parameter is
generally not changed from the factory test setting.
The Disable Scans Flag indicates that a compass scan over the target will not be run. Choosing “Yes”
will prevent scans from being run. This allows the controller to use the original heading source
instead of performing a SatTant or in the case where TLE tracking is used. If signal sources with good
satellite signal discrimination are going to be used and short acquisition times are essential, then the
time required to complete a SatTant under normal conditions may always be avoided by choosing
“Yes” for this parameter. Note: This will increase the probability of acquiring the wrong satellite if
the RSL signal source plays any role in the systems Acquisition or Peaking processes defined later in
this section.
